With the release of TGI 1.1.0 it is possible to load this model to a g5.48x on AWS.
But there seems to be a memory error when the model loads and tries to prefill.
Error repeats for both 4-bit and 3-bit versions, which is odd

Has anyone managed to deploy via TGI 1.1.0 on g5.48xlarge? I am seeing the same CUDA illegal memory access error during prefill:

Decreasing max-batch-prefill-tokens does not help resolve this error.

It seems that you need to adjust the max-batch-prefill-tokens value since you ran out of memory on the instance.

Any update on this? I'm still getting the same error on the g5.48xl with TGI 1.1.0 (8x24 GB VRAM) with the GPTQ version of falcon 180.
I tried down to 100 max prefill tokens and I still get "You need to decrease --max-batch-prefill-tokens"
How to estimate the extra memory requirement needed after the model is loaded ?

I'll be honest, I couldn't get the GPTQ version working on TGI 1.1.0, but 1.1.0 does support bitsandbytes-nf4 which did work for me on g5.48xl
My configuration is:

config = {
'SM_NUM_GPUS': json.dumps(8),
'MAX_TOTAL_TOKENS': json.dumps(2048 + 512),
'MAX_INPUT_LENGTH': json.dumps(2048),
'HUGGING_FACE_HUB_TOKEN': HUGGING_FACE_HUB_TOKEN,
'HF_MODEL_ID': 'tiiuae/falcon-180B-chat',
'HF_MODEL_QUANTIZE': 'bitsandbytes-nf4',
}
f_model = HuggingFaceModel(role=SAGE_ROLE, image_uri=LLM_CONTAINER, env=config)
predictor = hf_model.deploy(initial_instance_count=1, instance_type='ml.g5.48xlarge',
container_startup_health_check_timeout=900)

I think they had a problem with TGI 1.1.0 (https://github.com/huggingface/text-generation-inference/issues/1000), you could try 1.1.1 and see if resolved
